A = [-1 1 1 1; -1 -1 -1 1; -1 1 -1 -1; -1 1 1 -1; -1 1 1 -1];
B = A(:,1:2);
C = A(:,3:4);

Creating arrays from portions of a larger array using the index of the larger array will work for most any scenario, you just need to know what kind of indexing you're looking for. If you could elaborate more on what kind of separation you are looking to perform I could give a more comprehensive answer.
